Struct Pool 

pub struct Pool<T> { /* private fields */ }

Generic object pool for reusable objects

The pool maintains a collection of reusable objects to reduce allocation overhead. Objects are returned to the pool automatically via PoolGuard.

Implementations

impl<T> Pool<T>

pub fn new(capacity: usize) -> Self

Creates a new empty pool with the given capacity

pub fn get<F>(&mut self, create: F) -> T

where F: FnOnce() -> T,

Gets an object from the pool, or creates a new one if pool is empty

pub fn put(&mut self, obj: T)

Returns an object to the pool for reuse

If the pool is at maximum capacity, the object is dropped instead

pub fn clear(&mut self)

Clears all objects from the pool

pub fn len(&self) -> usize

Returns the number of objects currently in the pool

pub fn is_empty(&self) -> bool

Returns true if the pool is empty

Trait Implementations

impl<T> Default for Pool<T>

fn default() -> Self

Returns the “default value” for a type.
